Circadiant Releases IEEE802.3ae 850nm 10Gbase-SR compliant Stressed Eye Test blade for their Hydra Test Platform

New SR118 blade provides standards compliant 10Gbase-SR stressed signals for receiver sensitivity testing

Allentown, PA - Circadiant Systems, a leader in stressed signal testing, today announced the release of the SR118 blade for their Hydra Modular Test System – The new SR118 is an IEEE802.3ae 10G compliant stress generation blade that enables quick, easy and accurate 10Gbase10-SR optical receiver sensitivity testing in the versatile multi-port Hydra platform. The addition of the SR118 blade makes the Hydra platform a more valuable tool for 10GE developers and evaluators by providing IEEE802.3aq LRM, SFP+, IEEE802.3ae LR, SR and 10GE protocol testing in one system. The all-in-one solution solves industry issues of calibration, instrument drift, and system-to-system correlation.

SFP+ is emerging as the 10GE optical interface of choice for the enterprise market. The small form factor enables an increase in port density but brings technical challenges. The 10G analog signals are no longer contained in the optical module; they must now be transmitted out of the module, thru the connector and FR4 traces, to the EDC (Electronic Dispersion Compensation). The Analog signal transmission combined with port density poses a new list of challenges with dispersion and crosstalk. Stress testing multiple ports simultaneously will be imperative. The Hydra SR, LR or LRM stress generation blades can stand alone to provide inline testing for up to 10 channels in one Hydra system, or can be combined with our pattern generation blades to provide asynchronous 10GE traffic for multi-port testing./p>

Most SFP+ line cards support SR and LRM module types requiring compliance testing for both. With the addition of the SR118 blade the Hydra platform can now test limiting modules and host cards for both IEEE802.3ae SR and IEEE802.3aq LRM stressed receiver compliance.

“Our OST product line has become an industry standard for IEEE802.3ae stressed receiver sensitivity testing because of its broad range of functionality, but in some cases the customers needed a trimmed back, lower-cost version that could simply supply the standard stressed signals," said My Chung, Circadiant President and CEO “We are answering that need with the SR118 blade, our latest blade for the Hydra platform.”
